Description

Technical Field

[0001] The utility model relates to the field of pharmaceutical equipment, in particular to an injection water cooling device. Background Art

[0002] In the pharmaceutical industry, water for injection (commonly known as double distilled water) is a vital raw material, and its quality and purity are directly related to the safety and effectiveness of drugs. It is generally obtained by distillation or deionization and other process treatments. With the development of the pharmaceutical industry, the requirements for water for injection are getting higher and higher. Since the temperature of water for injection is usually high, it needs to be cooled before use, and it should be kept warm at 80°C or above or kept warm at 70°C or above during storage. Therefore, the cooling device for water for injection plays an indispensable role in pharmaceutical production. However, there are some "dead corners" in the cooling device for water for injection in the prior art that are difficult to be flushed by water flow, resulting in a slow flow rate of water for injection in these areas, and it may even stagnate and be unable to carry out normal water circulation, resulting in a decrease in water quality and the breeding of bacteria and other microorganisms. In addition, blind pipes often appear in the cooling device for water for injection. Since the water in the blind pipe cannot be flushed by the mainstream water flow, it is easy to form dead water. These dead waters are retained in the pipeline for a long time, which not only affects the water quality, but also may become a breeding ground for bacteria and other microorganisms, posing a potential threat to drug production.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0025] like Figures 1 to 4As shown, a cooling device for injection water comprises an injection main pipe 16 with injection water, an injection pipe 1 connected to the inside of the injection main pipe 16 and provided with a first water valve 12, a cold water pipe 7 provided at one end of the injection pipe 1 and provided with a second water valve 18, and a water outlet pipe 6 provided at the other end of the injection pipe 1 and provided with a third water valve 14; the injection pipe 1 is connected to the inside of the cold water pipe 7, and the injection pipe 1 is connected to the inside of the water outlet pipe 6.

A cold water pipe 7 is provided between the injection pipe 1 and the cold water pipe 7. The cooling pipe 4 is connected to the inside of the cooling pipe 4, and one end of the cooling pipe 4 is plugged with the outlet pipe 6 and connected to the inside. The first water valve 12 and the third water valve 14 are opened, and the injection water passes through the cooling pipe 4 and flows out from the outlet pipe 6; the third water valve 14 is closed, and the injection water is insulated and circulated between the injection pipe 1, the insulation pipe 8 and the cooling pipe 4; the cold water pipe 7 is used for cold water to flow into and cool the injection water, and the cold water pipe 7 is connected to the injection pipe 1 through the cooling pipe 4; the first water valve 12 is opened to allow the injection water to flow into the cooling pipe 4 through the injection pipe 1, and the injection water to flow into the outlet pipe 6 through the cooling pipe 4, and the second water valve 18 is opened to allow cold water to flow into the cooling pipe 4 through the cold water pipe 7 to cool the injection water.

[0026] It is worth noting that the water for injection is liquid water with a temperature of 70°C to 100°C, and the cold water in the cold water pipe 7 is liquid water with a temperature of 40°C to 0°C.

[0027] like Figures 1 to 4As shown, a first water injection pipe 2 is provided between the injection pipe 1 and the cooling pipe 4, a fourth water valve 11 is provided on the first water injection pipe 2, a third water injection pipe 9 is provided between the cold water pipe 7 and the water outlet pipe 6, one end of the insulation pipe 8 is communicated with the inside of the third water injection pipe 9, a sixth water valve 13 is provided on the third water injection pipe 9, a second water injection pipe 15 for communicating with the third water injection pipe 9 is provided at one end of the cooling pipe 4, wherein a thermometer 10 is provided on the second water injection pipe 15; in this embodiment, one end of the injection pipe 1 is connected with an injection main pipe 16 for injecting water for injection, and one end of the injection main pipe 16 is communicated with the inside of the insulation pipe 8, the thermometer 10 is used to detect the real-time temperature of the water for injection, and the cooling pipe 4 is connected with the insulation pipe 8. The injection water cooled in the cooling tube 4 enters the third water injection pipe 9 through the second water injection pipe 15, and enters the water outlet pipe 6 through the third water injection pipe 9. The fourth water valve 11 is used to control the water injection pipe 1 to supply water to the cooling tube 4. By closing the fourth water valve 11, the injection water can flow into the insulation tube 8 through the injection pipe 1 for storage. In actual use, the sixth water valve 13, the fourth water valve 11 and the first water valve 12 are opened, so that the injection water can enter the injection pipe 1, the cooling pipe 4 and the insulation tube 8 through the injection main pipe 16, and finally flow back into the injection main pipe 16 for insulation circulation, and the temperature is detected in real time by the thermometer 10, which is convenient for users to observe and use.

[0028] like Figures 1 to 4As shown, the cooling pipe 4 is provided with a water injection cavity 21 and an interlayer cavity 20 arranged outside the water injection cavity 21, and the interlayer cavity 20 is used to communicate with the inside of the cold water pipe 7, wherein a first adapter 3 is provided between the first water injection pipe 2 and the cooling pipe 4, and a second adapter 5 is provided between the cooling pipe 4 and the second water injection pipe 15, and the first adapter 3 and the second adapter 5 have the same shape and structure, and the inner cavity of the first adapter 3 is provided with a plurality of capillaries 22 for connecting with the water injection cavity 21, and the cooling pipe 4 is close to the first adapter 3. One end is provided with a drainage pipe 17 for communicating with the interior of the interlayer cavity 20, and a fifth water valve 19 is provided on the drainage pipe 17; in this embodiment, one end of the cold water pipe 7 can be connected to the tap water outlet pipe so that the cold water connected to the cold water pipe 7 is tap water, one end of the drainage pipe 17 is connected to the tap water inlet pipe, and the cold water pipe 7, the interlayer cavity 20 and the drainage pipe 17 are connected to each other in sequence to form a cooling circulation system, and the fifth water valve 19 is used to control the drainage of the drainage pipe 17. In actual use, The injection water flows into the water injection chamber 21 through the capillary 22, the second water valve 18 is opened, the fifth water valve 19 is opened, and the cold water in the cold water pipe 7 enters the interlayer chamber 20, thereby generating heat exchange through water circulation to quickly cool the injection water in the water injection chamber 21. The user observes the real-time temperature display of the thermometer 10 and can adjust the cooling temperature of the injection water by adjusting the second water valve 18 to control the amount of cold water entering the interlayer chamber 20, thereby reducing the operation difficulty of this embodiment. When the user adjusts the required temperature, the sixth water valve 13 is closed and the third water valve 14 is opened, so that the injection water passes through the first water injection pipe 2, the cooling pipe 4, the second water injection pipe 15, and the third water injection pipe 9 in sequence to enter the water outlet pipe 6, which is convenient for the user to use. After use, the user closes the second water valve 18, the fifth water valve 19, and the third water valve 14, and opens the sixth water valve 13, so that the injection water circulates again between the injection pipe 1, the insulation pipe 8 and the cooling pipe 4, effectively avoiding the existence of dead water in all water pipes in this embodiment.

[0029] It is worth noting that the cold water after heat exchange re-enters the tap water inlet pipe through the drainage pipe 17. Due to the provision of the interlayer chamber 20 and the water injection chamber 21, the cold water in the cold water pipe 7 cannot directly contact the water for injection, resulting in contactless water circulation cooling, avoiding chemical reaction between the cold water and the water for injection, so that the cold water entering the tap water inlet pipe can be directly drunk again, avoiding waste of water resources; after cooling, close the second water valve 18, so that the cold water in the interlayer chamber 20 is completely discharged into the tap water inlet pipe through the fifth water valve 19, effectively avoiding the generation of dead water in the interlayer chamber 20, and further improving the user experience of this embodiment.

[0030] Working principle: When the injection water is insulated and circulated, the sixth water valve 13, the fourth water valve 11 and the first water valve 12 are opened, and the other water valves are closed. The injection pipe 1, the insulation pipe 8 and the water injection chamber 21 are connected in sequence to form an insulation circulation system, and the injection water circulates and flows insulatedly among the injection pipe 1, the insulation pipe 8 and the water injection chamber 21.

[0031] When injection water of appropriate temperature is needed, the fourth water valve 11, the first water valve 12, the second water valve 18 and the fifth water valve 19 are opened, and the sixth water valve 13 is closed. The injection water is sequentially poured into the injection pipe 1, the first water injection pipe 2, the water injection cavity 21, the second water injection pipe 15 and the third water injection pipe 9. The cold water pipe 7, the interlayer cavity 20 and the drainage pipe 17 are sequentially connected internally to form a cooling circulation system. Tap water circulates in the cold water pipe 7, the interlayer cavity 20 and the drainage pipe 17 to cool the injection water in the water injection cavity 21. The thermometer 10 detects the temperature of the injection water in real time. Then, the switch size of the second water valve 18 is adjusted to adjust the flow rate of cold water in the cold water pipe 7 to adjust the amount of cold water in the interlayer cavity 20, thereby adjusting the temperature of the injection water. After the required temperature is displayed on the thermometer 10, the third water valve 14 is opened to use the injection water cooled to an appropriate temperature.

[0032] After the injection water is used up, close the second water valve 18, the fifth water valve 19, the third water valve 14, and open the sixth water valve 13, so that the injection water circulates again between the injection pipe 1, the insulation pipe 8 and the cooling pipe 4, and there is no dead water in all pipes.
